Why can’t governments insist that all passengers traveling across international frontiers must be screened before boarding? If all passengers had to get a clean bill of health two days before flying, this would reduce fear and slow the spread of the disease from country to country.
Sure some people would slip through the net but it would allow commerce, travel and business to continue with some increased factor of safety. Of course, some countries are without adequate testing regimes would struggle and some countries do not provide universal health care but it seems worth a though to me.
